CAR-AXLE LUBRICATOR.

EJFICIPICATION forming part of Letters Patent No. 320,343,6latec1 June16, 1885.

Application filed April 28, 185. (No model.)

120 a l whom, 116 may concern:

Be it known that we, IsAiE FRI'JOHETTE and OHARLEs LoUIs GIRARD, both ofthe city of St. Hyacinthe, in the county of St. Hyacinthe, Province ofQuebec, Canada, have invented new and useful ln'iprovements inLubricators for RailwayCarAxles, &c.; and we do hereby declare that thefollowing is a full, clear, and exact description of the same.

This invention has reference to the construction of a lnbricator for thejournals of axles of railway-cars and other journals, arranged so thatthe said hibricator may be readily placed in the axlebox and removedtherefrom while the axle is in its position in the said axle-box.

The particular features which form our invention will be hereinafterfully set forth and claimed.

In the drawings hereunto annexed, similar letters of reference indicatelike parts, and Figure 1 is a side elevation of a lubricator embodyingthe invention. Fig. 2 is a plan of the lubrieator shown in Fig. 1. Fig.3 is an end elevation of the lubricator shown in Fig. 1; Figs. A, 5, and6 are details of construction.

Letter A represents a frame made,as shown, to fit loosely within thelower part of the axlebox 13.

O is the axle,shown at the relative position with the bottom of theaxle-box that they are ordinarily placed in. The upward extensions D oftheframe A are for the purpose of steadying the lower part of the frameupon the bottom of the axle-box, or, in other words, to prevent anydanger of the frame A becoming canted up or raised from the bottom ofthe axle-box B by the action of the working parts attached upon it.

Upon the frame A, by eyesEor similar contrivances, is attached an axis,F, having two arms, G, secured on the axis F or made integral therewith.On the part of the axis F situated between the two arms G, the axis isenlarged, and in this enlargement a circumferential groove, H, isformed. The upper ends of the arms G terminate in eyes K,through On thispin is situated a grooved roller, L, arranged to freely revolve on thesaid pin 1. The groove M of the roller L is preferably of Vconfiguration,

and provided with ordinary projections, N, (see Fig. 6,) for impartingthe motion of the roller L positively to a chain, 0, which passes overthe said roller and the hereinbefore-mentioned groove 11. (See Figs. 1,2, and 3.)

From the above description it will be understood that the roller L andchain 0 upon it are free to rotate upon the axis F, as indicated by theare of a circle, P, in Fig. 1, while at thesame time by pressing theperiphery of the roller L against the periphery of the axle G the rollerL is revolved by theaxle 0, cansing the chain 0 to travel aroundin thegrooves H and H, so thatif the lower part of the axleboxB is filled withfluid-lubricating material to such a level as that the lower part of thechain 0 will be immersed in it, the lubricating material will be carriedup by the chain 0 into the groove M, and thence spreads upon the rollerL and by it distributed upon the axle 0.

As the space for getting the invention into the axlebox under the axleis very much confined in the case of railway-car axles, and more so onaccount of the outer collar with which nearly all railway-car axles areprovided, it is necessary to make the arms G capable of swinging, ashereinbefore stated and indicated by the are of'a circle, 1?, iurneddown to or a. little below the position indicated by dotted lines inFig. 1, thus enabling the invention to be passed with comparative easeinto and out of the axle-box when desired, so that should the inventionbe found defective by wear, 10., it can be readily removed and repaired,or replaced by a new one, as desired.

It has been hereinbefore stated or inferred that the roller L is to bepressed up against the axle O, and by its capability of being pressed byswinging on the pivot-axis F such swinging will enable the part tocompensate for the difference of position of the axle 0 caused by itswear and that of the bearing upon which it ordinarily works,for anychange of said position from any other cause.

For the purpose of pressing the periphery of the roller L against theperiphery of the axle C, an almost countless multitude of variety ofsprings, and even weights, may be arranged. \Ve shall, however, confineourselves to showing in the drawings, and shall confine thisspecification to describing,..only one method or arrangement of spring,and consider that to be sufficient to cover all the other arrangementsfor this said purpose.

On any suitable bar, A, secured in the frame A, a coil-spring, B, issecured. This coil-spring terminates, as shown, in an eye, 0.

In one of the arms G an opening, D, (see Fig. 5,) is formed, a link, E,attaching the arm G to the eye 0. By this arrangement the tension of thespring B keeps the periphery of the roller L pressed with sufficientforce upon the periphery of the axle O, and enables the arms G to bereadily depressed, as indicated by dotted lines in Fig. 1, whenever itis desired to so depress them, which will be the case when the inventionis to be put in or taken out of the axle'box.

Fis a spring arm secured on one of the arms G, as shown, for keeping thepin I, upon which the roller L revolves, in place. Any other contrivancemay be arranged, such as a nut, for this purpose. Nevertheless, thespringarm F gives an important facility for readily removing andreplacing the pin I and roller L.

It will be remarked that the roller L is made with the parts of itsperiphery N next to groove M somewhat smaller in diameter than thediameter of the outer parts, N. This provides a space for a film of oilto form in, to touch the axle O and giveamuch betterlubrieating thanwould be obtained by surfaces coming into close bearing contact.

What we claim and wish to secure by Letters Patent is as follows:

1. The combination of the axle G, roller L, having groove M, arms G,axis F, having groove H, chain 0, operating-spring B, connected witharms G, and frame A, the whole constructed and arrangedsubstantially asand for the purposes set forth.

2. The combination of the pivoted and swinging arms G, roller L, havinggroove M, pin I, spring-arm F, chain 0, and spring B, arranged tooperate the said arms G,the whole constructed and arranged substantiallyas and for the purposes set forth.
